Vancouver, BC – Vancouver-based Lululemon Athletica Canada Inc. is accusing Costco Wholesale Corp. of infringing on its intellectual property by selling knockoffs of some of its most popular products

A lawsuit recently filed in a California court alleges that Costco sells dupes of Lululemon’s Scuba hoodies and sweatshirts, Define jackets, and ABC pants.

Some of the alleged fake items identified by Lululemon are sold under Costco’s private label Kirkland, but others are made by manufacturers like Danskin, Jockey, and Spyder.

The lawsuit states, “Some customers incorrectly believe these infringing products are authentic Lululemon apparel, while still other customers specifically purchase the infringing products because they are difficult to distinguish from authentic Lululemon products, particularly for downstream purchasers or observers.”

Lululemon alleges that these scenarios take advantage of the patents it holds, as well as the reputation and goodwill it has built with customers.
